今天在整合mybatis和spring的时候出的错 报错如下

报错原因是因为我在mybatis里面这段代码没有删除导致spring和mybatis都扫描了一遍xml,就出错了。
<mappers> <mapper resource="cn/dao/WorkinggMapper.xml"/> </mappers>
这两段代码只要删一段就行,删spring里面的或者mybatis的都行
<!-- 配置SQL映射文件信息 --> <property name="mapperLocations"> <list> <value>classpath:cn/dao/**/*.xml</value> </list> </property>
